Scrub and pierce the sweet potato and microwave it on high until soft,
about 10 minutes. Peel and puree in a blender or food processor. (Or you can cut the potato in half, scoop out the meat, and mash it with a fork.) Measure
out 1 cup.

Prepare the complete Ham in Sweet Potato Biscuits recipe as
above, cool, and wrap the sandwiches in foil. When it's time to serve,
reheat them in a warm oven, still wrapped in foil, for about 10 minutes.
